A rollover request in Elasticsearch 6.2.0 or later will be aborted if the same alias is found in the matching index templates.

Starting in Elasticsearch 6.2.0, JVM GC logging is enabled out of the box. This lightweight facility gives insight into GC issues. The settings for this are in jvm.options and default to keeping 2 GB worth (rotating every 64 MB) of logs in the default logs directory. If you are upgrading from a previous version of Elasticsearch and preserve your existing jvm.options, you should add the following..

However, /tmp is public so we have elected to change the packaging so that we use a private temporary directory. If you are upgrading from a previous version of Elasticsearch and preserve your existing jvm.options, you should add the line -Djava.io.tmpdir=${ES_TMPDIR}. It is safe to d..

A custom security policy can be applied and one permission that can be added to this policy isjava.security.AllPermission. However, this effectively disables the..

Bootstrap checks now apply to link-local addresseseditPreviously when Elasticsearch was bound to localhost, Elasticsearch would bind to any address on the loopback device. This included link-local addresses on the loopback device such as fe80::1%lo0on macOS. Starting in 6.1.2, Elasticsearch will now only bind to loopback addresses on the loopback device. Because of the previous behavior, Elastic..
